Hello Jean-François, it doesn’t look glorious, especially on Monday! In the meantime, Sunday will still be acceptable with some light rain in the early morning; then cloudy but generally dry weather over the hours. The followingnoon will perhaps see a few gaps under a fairly strong south-westerly wind and highs of 11-12°C. Monday will be very gloomy and windy with often continuous rains and gusts of 65 to 80 km/h, before a slight lull in the rains in the evening (13-14°C maximum). A drop in the mercury is expected on Tuesday in contact with showers which will gradually become rare in the followingnoon, it will still be necessary to keep the umbrella and the big coat since we will once more lose 5 to 7°C.
And on the rest of the country?
Finally the sun is back! The latter will be present on Saturday morning with a very blue sky and great conditions despite the cold. Unfortunately, it will have a hard time raising the mercury, which will hardly exceed 2 to 3°C in the middle of the morning on the plain. Then, a slight instability will cause the formation of cumulus clouds flattened by the anticyclone, sometimes masking the sun, especially north of the capital (quite sunny in the south of the Ardennes).
Afternoon, there will always be this alternating sky with beautiful periods of sunshine and sometimes numerous cumulus clouds but without showers. After 3-4 p.m., other high clouds will arrive from Flanders and France on the sidelines of a weak warm front which will still be harmless even if it will cover everywhere in the evening. We will reach very timid highs of 2 to 7°C, under a light wind from various directions, with a preference for the southwest. In the evening, we will have a few drops at sea, then on a Hainaut-Brabants axis, then on Namur at the start of the night and on the Ardennes at the end of the night with a few snowflakes.
